THS4032 (ACTIVE)

100-MHz Low Noise Voltage-Feedback Amplifier, Dual

 

Description

The THS4031 and THS4032 are ultra-low voltage noise, high-speed voltage feedback amplifiers that are ideal for applications requiring low voltage noise, including communications and imaging. The single amplifier THS4031 and the dual amplifier THS4032 offer good AC performance with 100-MHz bandwidth (G = 2), 100-V/µs slew rate, and 60-ns settling time (0.1%). The THS4031 and THS4032 are unity-gain stable with 275-MHz bandwidth. These amplifiers have a high drive capability of 90 mA and draw only 8.5-mA supply current per channel. With –90 dBc of total harmonic distortion (THD) at f = 1 MHz and a very low noise of 1.6 nV/√Hz, the THS4031 and THS4032 are designed for applications requiring low distortion and low noise such as buffering analog-to-digital converters.
